Section 10 is of interest and says:
"The speed at which the fully loaded survival craft or rescue boat is lowered to the water shall not be less than that obtained from the formula:
S = 0.4 + 0.02H where S is the lowering speed in meters per second and H is the height in meters from the davit head to the waterline with the ship at the lightest sea-going condition.
The maximum lowering speed shall be established by the Administration having regard to the design of the survival craft or rescue boat.
"The launching mechanism shall be so arranged that it may be actuated by one person from a position on the ship's deck and, except for secondary launching appliances for free-fall lifeboats, from a position within the survival craft or rescue boat. When launched by a person on the deck, the survival craft or rescue boat shall be visible to that person.
The winch brakes of a launching appliance shall be of sufficient strength to withstand:
a static test with a proof load of not less than 1.5 times the maximum working load;
a dynamic test with a proof load of not less than 1.1 times the maximum working load at maximum lowering speed.
("Dynamic test" is stopping the boat while lowering fully loaded at the recommended speed.)
An efficient hand gear shall be provided for recovery of each survival craft and rescue boat."
